{"product_id":"allen-bradley-52-66063-52-853594t-clutch-dog","title":"Allen-Bradley 52-66063, 52-853594T Clutch Dog","description":"\u003cdiv\u003e\u003cp\u003eThis OE-numbered clutch dog, 52-853594T, is an aftermarket replacement for the MerCruiser Alpha One lower unit, providing the essential shifting component that engages forward gear inside the gearcase and restores proper drive engagement. It is used in Mercury\/MerCruiser Alpha One Gen 1 and Gen 2 stern drives, including the R and MR sterndrive configurations, where the clutch dog is the mating piece in the dog‑clutch that controls forward engagement. Catalog and aftermarket listings show cross-references such as 824112 and 52-66063, with 52-66063 appearing in older MerCruiser gear housing references and 824112 appearing as an additional OEM\/replacement cross-reference, reflecting how this part is cataloged across sources. Retailers describe it as a direct replacement for the OEM clutch dog in these lower units, making it a common option for MerCruiser service and repair workflows aimed at restoring smooth shifting and reliable engagement without replacing the entire gearcase. When sourcing, verify alignment with your Alpha One Gen I or Gen II lower unit and note that multiple aftermarket listings may use the same OE number to indicate compatibility with MerCruiser gearcases used in Alpha One sterndrives.\u003c\/p\u003e\u003c\/div\u003e","brand":"Aftermarket","offers":[{"title":"New Surplus No Box","offer_id":51657076900142,"sku":null,"price":58.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_ceb47711-560c-49f7-bcb8-140c375d2583.jpg?v=1769465851","url":"https:\/\/plgautomation.com\/products\/allen-bradley-52-66063-52-853594t-clutch-dog","provider":"PLG Automation ","version":"1.0","type":"link"}
